Challenge  A cell phone plan costs $22.90 per month for 500 minutes of talk time. It costs an additional $0.04 per minute for each minute over 500 minutes. To get e-mail access, it costs 20% of the price for 500 minutes of talk time. Your bill, which includes e-mail, is the same each month for 5 months. The total cost for all 5 months is $155.00. Write and solve an equation to find the number of minutes of talk time you use each month. Let m represent the number of minutes over 500 minutes each month. Which equation represents the given situation?
A.
155.00=5(0.04m+22.90+0.20(22.90)) B.
155.00=5(m+22.90+0.80(22.90))
C.
155.00=5(m+22.90)
D.
155.00=5(0.04m+22.90)
